@Shadrach. To be clear, I WANT you to interfere. I want and need your advice.
At this point I figure she knows. I'm going to let her hatch in the big coop.
I removed the eggs she had been sitting on and replaced them with the fertile ones. 3 for 3. What I did not consider was others adding to her nest. How do you mark yours?
I have not considered that. I am going to install a broody cam focused right on her nest box to help with keeping an eye on her. I will consider a wire mess. That is an interesting idea.
I am pulling food from the coop. I need to set up alternate feeding stations for Phyllis now. That will be fun tonight.
Understood.
Thanks again for your help. This is exactly what I need to know. I have no knowledge and/or experience with broodies.
